BOTTLE-STOPPER.

Application filed April 26, 1915. Serial No. 23,809.

To all whom it may concern:

Be it known that I, JAMES CAMro, a c1t1- zen of Italy, residing at Stafford sp flngs, in the county of Tolland and State ofConnecticut, have invented certain new anduseful Improvements in Bottle-Stoppers, of which the following is a specification.

My invention relates to. an improved botand is particularly adapted for bottles containing charged or effervescent liquid to be dispensed from time to t1me.

At present, charged liquids are generally supplied in comparatively small bottles, because of the difficulty of preventing the escape of gas from large bottles after the receptacle has once been. opened. This applies to all kinds of charged liquids except selters andthe like, the bottles containing which -are provided with expensive discharge caps. Those liquids which are hottled in receptacles that are closed by the ordinary crown seals must be consumed practically as soon as the bottle is opened in order to avoid the deterioration above suggested.

The principal object of my invention is to provide a form of stopper which is especially designed for use in connection with bottles closed with crown seals, the said stopper protecting the contents of the bottle after the latter has been opened, the liquid retaining its gas charge for a practically indefinite time.

Two. forms of the invention are illustratively exemplified in the accompanying drawing, in which- Figure 1 is a vertical sectional view of the preferred form of stopper applied to a bottle, a fragment. of the latter being shown; Fig. 2 is a side elevational view of the stopper shown in Fig. 1; Fig. 3 is a perspective view of a metal cap which I prefer to place over the bottle mouth and upon which my improved stopper is superimposed; Fig. 4 is a similar view to Fig. 1 of a modified form of the invention, and Fig. 5 is a vertical sectional view on the line 55 of Fig. 4.

Referring to the drawing," and more particularly to Figs. 1 we thereof, 10'denotes the neck of a bottle, the mouth of which is provided with an ordinary crown seal 11. This seal usually consists of a metal disk having its edge crimped down over the outside of the flange 12 of the bottle neck.

The improved'stopper proper comprises a resilient cushion13, preferably of rubber,

and approximately the shape of the bottle neck. Superimposed on the cushion 13 is a metal neck 14 having the depending 'sleeve or skirt 15 which envelops the cushion 13 and is providedwith" a clamp .16. The

clamp pivotally supports, at 17, a cam lever v 18 by means of which the clamp maybe secured to and freed from the bottleneck. The interior of theneck 14 is threaded to receive a correspondingly threaded depending sleeve "19 formed integrally with the stopper head 20. The neck 19 is hollow and communicates' with the outlet 21 formed laterally in the head 20. Also removably secured to the'lower end of the neck 19,\as

by'means of screw threads, is a. cutter 22 which may be of annular or prismatic or other suitable form, as preferred. The cut-, ter normally projects below the lower plane of theupper horizontally disposed portion of the rubber cushion 13, and above the cutter is-a screen 23 to prevent any solid particles from passing out of the bottle through the outlet 21.

The head 20 is provided with a depending flange 2 1 acting as astop and seat for a valve 25 which is normally pressed against the seat 24 by a coiled spring 26, one .end ofwhich spring rests against the screen 23 and .the other end of which engages said valve 25. Threaded into the valve 25 is a valve rod or stem 27 which projects up into the head 20 and passes through suitable packing 28. The upper end of the valve stem 27 is pivotally connected to an operating lever 29 which may be elevated to depress the valie 25 and permit liquid to issue through the outlet 21.

Fig. 3 discloses a metallic cap'which :I prefer to place over the sealed bottle before applying my improved stopper. this cap serving to prevent injury to the rubber cushion 13 by any sharp edges which may be produced in the crown seal when the latter 15 disrupted by the cutter 22." This metallic cap is practically a ring 30 having a depending slotted flange 31 which engagesthe flange 12 of the bottle neck.

, In the modified form of invention shown in Fig. 4, the structure is substantially similar to that of the preferred form, exce t that the. spring 26 of Fig. 1 is complete y housed within the stopper head. In Fig. 4, I may, if desired, dispense with the cutter shown in the preferred form, and disrupt the crown seal by meansof a knife or other suitable instrument;

Referring to Fig. 4, .10 denotes the bottle neck having the external flange 12 13 denotes the rubber cushion embraced by the sleeve 15 depending from the head '20 of the stopper. 21 is the stopper outlet; 24* denotes. the depending flange within the head against which the valve 25 seats. 27 is the valve rod or stem which projects up into the head 20 and is surrounded near its upper portion by the spring 26* contained in a suitable bore 40 in the stopper head. 29 is the operating lever for the valve. 16 is the clamp, and 18 the clamp lever carried on the pivot 17 for securing the stopper "to and releasing it from the bottle. Y r

The operation of the device may be briefly described as follows :I first place thering 30 over the crown 11 of the bottle 10. I then unscrew the head 20 and sleeve 19 together with the cutter 22 from the heck 14, and then place the neck 14 with its contained rubber cushion and attached clamp 16 over the bottle head. The clamp lever 18 is then operated to clamp the cushion and sleeve 15 about the bottle head. Thereafter the head and cutter are screwed into place, by which action the cutter disrupts the crown seal 11, and as the cutter is worked down the rubber cushion 13 may becorrespondingly moved down on the bottle head by alternately opening and closing the valve 25 which has been depressed by the depression of the lever, is automatictlly reseatedagainst the flange 24 and the bottle is thus again stoppered. In this manner all accidental escape of gas or discharge of fluid is avoided.

Havin thus described my invention, what I c aim is 1. Ina stopper for receptacles designed to contain charged liquids, the combination having a discharge outlet, a valve seat within said head, a valve operable within said head and in position to have the pressure Within the bottle cooperate in holding said valve to said seat, means for unseating said valve, means within the head for disrupting a bottle stopper, a flexible skirt depending from said head and adapted to embrace the bottle neck; and means for tightly clamping said skirt to said receptacle.

2. In a stopper for receptacles designed to contain charged liquids, the combination of a head adapted to be placed over the receptacle mouth and having a passage therethrough in direct communication with the interior of the receptacle, said head also having a. discharge outlet, a valve seat within said head, a valve operable within said head and in position to have the pressure within the bottle cooperate in holding said valve to said seat, means for unseating said valve, a spring for initially pressing said valve to said seat, means within the head for disrupting a bottle stopper, a flexible skirt depending from said head and adapted to embrace the bottle neck; and means for tightly clamping said skirt to said receptacle.

3. In a stopper for receptacles designed to contain charged liquids, the combination of a head adapted to be placed over the receptacle mouth and having a passage therethrough in direct communication with the interior of the receptacle, said head also having a discharge outlet, a valve seat with- .in said head, a valve operable Within said head and in position to have the pressure within the bottle cooperate in holding said valve to said seat, means for unseating said valve, means within the head for disrupting a bottle stopper, a flexible skirt depending from the head and adapted to embrace the bottle neck,'means"for tightly clamping said skirt to said receptacle, and cushioning means interposed between the stopper and the receptacle neck. I

In testimony whereof I have .afiixed my signature in presence of two witnesses.
